Architecture and implementation of a dynamic RMI server configuration hierarchy to support federated search and update across heterogeneous datastores

Abstract

An architecture and implementation of a dynamic RMI server configuration hierarchy to support federated search and update across heterogeneous datastores. The RMI server configuration hierarchy supports searching for data in one or more heterogeneous data sources within a computer system. A request for data is received at a federated data source. Then, a server is selected to process the request based on a load of the server and based on whether the server can satisfy the request for data.

AI Technical Summary

Benefits of technology

[0032]According to an embodiment of the invention, the RMI server configuration hierarchy supports searching for data in one or more heterogeneous data sources within a computer system. A request for data is received at a federated data source. Then, a server is selected to process the request based on a load of the server and based on whether the server can satisfy the request for data.

Problems solved by technology

However, business data represents only a small part of the world's information.

Multimedia data, on the contrary, cannot be fully pre-structured (its use is not fully predictable) because it is the result of the creation of a human being or the digitization of an object of the real world (x-rays, geophysical mapping, etc.) rather than a computer algorithm.

Classical business computer systems have not been designed to directly store such large objects.
